Problems solved by technology

[0007] Due to the overlapping of multiple parts in the power battery housing assembly of a pure electric car, it is easy to cause poor sealing, especially at the corner position. In the prior art, the connecting piece connecting the two parts is generally directly welded on the connect the top of the two parts and then proceed to glue the

Embodiment Construction

[0031] For clarity, the following description will be combined with a Cartesian coordinate system, in which whether in the front-to-rear direction or the left-to-right direction, the side closer to the origin O is the inner side, and the side further away from the origin O is the outer side.

[0032] reference figure 1 , The power battery housing assembly 1 of a pure electric car is used to arrange the power battery in the bottom space of the car.

[0033] reference figure 2 In this embodiment, the power battery housing assembly 1 uses at least two bottom plates 9, and the two bottom plates 9 are connected by the middle longitudinal beam 3 and the tray 5. When the middle longitudinal beam 3 and the tray 5 are not present, a whole bottom plate 9 can also be used. In this embodiment, the middle longitudinal beam 3 is a sealed box-shaped structure, which can strengthen the structural strength of the power battery housing assembly 1. The upper surface of the middle longitudinal beam ...

Abstract

The invention provides a power battery housing assembly for an electric automobile. The power battery housing assembly comprises a base plate, an outer plate and a plurality of connecting pieces, wherein the outer plate is fixed to the base plate and surrounds the base plate to form a power battery accommodating space. The outer plate comprises a front beam outer plate, a rear beam outer plate, a left longitudinal beam outer plate and a right longitudinal beam outer plate. The connecting pieces are respectively located at the corner position connected with the front beam outer plate and the left longitudinal beam outer plate, the corner position connected with the front beam outer plate and the right longitudinal beam outer plate, the corner position connected with the rear beam outer plate and the left longitudinal beam outer plate and the corner position of the rear beam outer plate and the right longitudinal beam outer plate. The upper surfaces of the connecting pieces and the connecting pieces and the upper surfaces of the outer plates connected with the connecting pieces are on the same plane. The sealing performance of the power battery housing assembly can be guaranteed.

Description

Technical field [0001] The invention relates to the field of pure electric cars, in particular to a power battery shell assembly of a pure electric car. Background technique [0002] The power battery assembly of a pure electric car includes key components such as battery modules, BDU (battery cut-off unit), and LBC (centralized management system) controller. Since most of the current pure electric cars are developed on the basis of the original diesel locomotives, generally speaking, without sacrificing the passenger compartment space and the comfort of the vehicle, the space under the vehicle body becomes the total power battery of the pure electric car. The main space for layout. Limited by the layout space, designing a power battery shell assembly that not only meets the load-bearing capacity, anti-collision, and good sealing performance is the best solution for the industrialization of pure electric cars. [0003] The power battery shell assembly of a pure electric car carri...
